# --description--

Lengo sasa ni kufanya `div` isichukue upana mzima wa ukurasa. Sifa ya CSS `width` inafaa kwa hili.

You can use the `id` selector to target a specific element with an `id` attribute. An `id` selector is defined by placing the hash symbol `#` directly in front of the element's `id` value. For example, if an element has the `id` of `cat` then you would target that element like this:

```css 
#cat {
  width: 250px;
}
```

Use the `#menu` selector to give your element a width of `300px`.

# --hints--

You should have a `#menu` selector.

```js
const hasDiv = new __helpers.CSSHelp(document).getStyle("#menu");
assert(hasDiv);
```

You should set the `width` property to `300px`.

```js
const hasWidth = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style.width === '300px');
assert(hasWidth);
```

Your `div` should have a width of 300px.

```js
const divWidth = new __helpers.CSSHelp(document).getStyle("#menu")?.getPropertyValue('width');
assert(divWidth === '300px');
```
